class to hold linear ring topology (without attributes)
Objects can be created by calls to the function SpatialRings
rings:Object of class "list"; list elements are
all of class Ring-class
bbox:Object of class "matrix"; see Spatial-class
proj4string:Object of class "CRS"; see CRS-class
Class "Spatial", directly.
Methods defined with class "SpatialRings" in the signature:
signature(obj = "SpatialRings"): select subset of (sets of) rings; NAs are not permitted in the row index
signature(x = "SpatialRings", y = "missing"): plot rings in SpatialRings object
signature(obj = "SpatialRings"): retrieves the bbox element
signature(object = "SpatialRings"): retrieves the coords element from Ring objects in rings slot
signature(object = "SpatialRings"): retrieves coordinate names
signature(object = "SpatialRings"): retrieves the ID element from Ring objects in rings slot
signature(obj="SpatialRings", x="character"): replaces ID element
signature(from = "SpatialRings", to = "SpatialPoints"): ...
